Falling Mountain landslide

During the magnitude 7.1 Arthur’s Pass earthquake on 9
March 1929, a 900-metre-high section of mountain peak
collapsed onto Taruahuna Pass, close to the epicentre.
The landslide continued partway up the flanks of Mt
Franklin opposite. It then slid about 5 kilometres down
the remote valley of the west branch of the Otehake
River. The collapsed peak was later dubbed Falling
Mountain.
